Hi

I have a simple dropdown with a toDropdownMap-function. It looks like this:

DataObject::get('Employee')->toDropdownMap('ID','NickName', 'Choose employee')

Now, would it be possible, to show two or more Fields in the dropdown, like this?

DataObject::get('Employee')->toDropdownMap('ID','FirstName' . 'Surname', 'Choose employee').

So, instead of showing a nickname, I want to show firstname and surname...

Thanks

Joel

I'm pretty sure it will also check for methods called 'Nickname' on the object which can return and combination of fields.

If you had a function Nickname() { return $this->FirstName . ' '. $this->Surname; } (or if that doesn't work - getNickname()) then it should work. Though I am pretty sure the member object has a built in method like Fullname or Name which returns first name + surname so perhaps try those first before implementing your own

joelg - did you ever solve this problem? I've tried to add a method to ->todropdownmap('ID', 'Title') to add two fields instead of 'Title', but I can't get it to work.

If you are generating this for a list of Members (or a class that extends Member) then there is a method called "getName" that you can use to get First and Last names. So for example:

DataObject::get('Member')->toDropdownMap('ID','Name');

If you are using your own custom class, then WillR's technique should work fine.

PS: I have only tested this in 2.4.x, so can't comment on earlier versions.

Thanks for your reply. I'm trying to do this for two fields in another data object, so cannot use the inbuilt functions for "member".

I've solved it in the short-term by creating a new field combining the content of the two fields I want to display. But this isn't a very elegant solution.

Katy -
You add the function to the class you're getting rather than where you're getting it.

So in the case Joelg says it would be in the Employee Class itself

Also, ->toDropdownMap is now Deprecated, use ->map('ID', 'MyTitleFunction', '--empty--');

Have a look at: http://www.ssbits.com/tutorials/2010/dynamically-generating-a-dropdown-list/

That gives you a full tutorial on doing this stuff :)
